Usually, bimbofication is associated with IQ-reduction. And this is what most bimbofication files "promote". Indeed, what comes to mind first is Bambi.
I guess my first question is like, does the file need to be tailored specifically to trans women? There are numerous files like that out there which are directed at cis women. Like Ra is right that most bimbo stuff involves IQ loss.
Finding an exact match would be tough, but I can give some recommendations. 'Mind Mistress' has a series of files called Elegance. It's real conditioning that will make a person more appearance conscious. The first sets the triggers, the second would have the relevant suggestions. Her files are modular, so you could clip in the cock worshipping stuff and kind of build your own thing.
The Neural Nets/Pretty Pattern files might be good too. He uses women to voice versions of a lot of the files. Most are just fantasy, but there's some great training under the hood of some of them. Prolific selection too. Display Loop is one I like for those purposes.
The Librarian puts out a lot of stuff, and some of it would be great. But I think it's targeted to a sissy audience if you aren't careful about what you're looking at. "Vain and Slutty' would do the trick. I think it's a robot voice though.
This stuff should be available on RS. Commission is the safest route though. Lots of talented hypnotists out there, maybe a trans woman would be able to best address that kind of need. Lord knows we need the money. Good luck!
